[The use of ultrasonic amplitude histography in the diagnosis of chronic pancreatitis].

Ultrasound amplitude histography was used to evaluate structural disorders of the pancreas in patients with chronic pancreatitis. The amplitude histogram peak proved to be higher in chronic pancreatitis that in healthy subjects. The method enables to differentiate patients according to the severity of the disease characterized by the level of pancreatic enzyme-secretory insufficiency.

[Possibilities of using ultrasonography for intravital study of topographic anatomy of the anterior abdominal wall in humans].

The ultrasound investigation has been performed by means of the echodevices "Aloka-280" and "Aloka-650" (Japan), transducers of 3.5 and 5 MHz. Eighty-two persons of both sex at the age 16-72 years have been examined.

[Comparison of ultrasonic and clinico-functional indicators of the status of the pancreas in patients with chronic pancreatitis].

Upon examination of 85 patients with chronic recurrent pancreatitis there appeared a clear cut correlation between the ultrasonic findings and clinical, laboratory and intraoperative evidence indicative of chronic pancreatitis. It should be noted that ultrasonic amplitude histography was a pilot experience in relation to pancreatic investigation. Ultrasonic criteria as a whole were insufficiently informative for definite recognition of the disease phase (aggravation or remission of chronic pancreatitis), while the peak value of ultrasound amplitude histogram of the pancreas allowed differentiation of the severity (moderate or grave) of the excretory pancreatic insufficiency.

[Tubulointerstitial changes in patients with a history of hemorrhagic fever with renal syndrome].

Altogether 85 patients with a history of hemorrhagic fever and the nephrotic syndrome (HFNS) were examined at different stages after the disease, characterizing the status of the tubulointerstitial apparatus of the kidneys. Almost half of the patients who suffered this disease manifested a decrease in the capacity of the kidneys for osmotic concentration of urine under the conditions of deprivation for 36 hours, and in acid-secretory function of the kidneys under induced acidosis and clearance of uric acid. Ultrasonic studies demonstrated that part of the patients had uni- or bilateral indurations in the renal parenchyma.
